I got this CPU I want to give one more year (or two) of gaming life.
It is a AMD 4800+ X2 at 2.4Ghz G3 Stepping.
I know ive posted this on the Overclocking forum, but seems nobody seemed to have a opinion.
So, im posting here, where ive posted many times aswell.
At stock values the Core Temp (HWMonitor) is 22-25º under load.
At 2.9Ghz it hits the 28º. No voltage was messed up. Still at 1.328v.
I read around the web this cpu can go at 3.2Ghz with no problem. Mine seems pretty stable so far.
Ive read one review that took him at 3.5Ghz, but they refered it was stable, but it could burn up any minute.
I have the following rig:
Athlon 4800+ X2 2.5Ghz G2 Stepping
4 GB DDR2 533Mhz
ATI 4850 512Ram with aftermarket cooler.
Asus Triton 70 (cooler)
I know it is not your legendaries Core cpus, but hey, I only overclocked when the machines were getting a bit outdated.
That is what im doing now. Im just tmapering with the HTT because honestly i have 533mhz rams and i want them that way.
I ask help to you guys if anybody had experience with these kinds of CPUs. Thank you.
I don't know what your cpu voltage and temps are now but 33c @ 1.328v is really good if you are approaching 3GHz.
Dropping the HT to x4 will not effect your overall performance. You should be able to go 1.375v but I'm not real familiar with that stepping - I think some folks have gone well over 1.4v but I try to stay under that voltage.
You should know when you 'hit the wall' with the cpu. With the Brisbanes your volts/temps will get out of control with little GHz in return.
Mixing your memory is holding you back, too, though the 4-4-4-12 timings are great. You are leaving some performance on the table overall because of your low ram speed.
At a 250MHz clock you will be over 3.1GHz with your HT at 1000MHz (x4). If you stick with the PC2-6400 at the '333MHz' ratio your overall ram speed will approach 750MHz - the memory divisor for the X2 4800+ is ""7"".
250MHz x 12.5 = 3125MHz / 7 = 446 x .8325 (333MHz ratio) = 373 x 2 or 746MHz ram speed.
To hit 3.2 ...
256MHz x 12.5 = 3200MHz / 7 = 457MHz x .8325 = 381 x 2 or 761MHz ram speed
(your HT @ x4 will be 1024MHz - you could drop back to x3 @ 768MHz - still faster than your ram speed)
